1. Business Problem

1.1 Problem Description

Netflix is all about connecting people to the movies they love. To help customers find those movies, they developed world-class movie recommendation system: CinematchSM. Its job is to predict whether someone will enjoy a movie based on how much they liked or disliked other movies. Netflix use those predictions to make personal movie recommendations based on each customer’s unique tastes. And while Cinematch is doing pretty well, it can always be made better.

Now there are a lot of interesting alternative approaches to how Cinematch works that netflix haven’t tried. Some are described in the literature, some aren’t. We’re curious whether any of these can beat Cinematch by making better predictions. Because, frankly, if there is a much better approach it could make a big difference to our customers and our business.

1.2 Problem Statement

Netflix provided a lot of anonymous rating data, and a prediction accuracy bar that is 10% better than what Cinematch can do on the same training data set. (Accuracy is a measurement of how closely predicted ratings of movies match subsequent actual ratings.)

1.4 Real world/Business Objectives and constraints

Objectives:

  1. Predict the rating that a user would give to a movie that he has not yet rated.
  2. Minimize the difference between predicted and actual rating (RMSE and MAPE)

Constraints:

  1. Some form of interpretability.

2. Machine Learning Problem

2.1 Data

2.1.1 Data Overview

Get the data from : https://www.kaggle.com/netflix-inc/netflix-prize-data/data

Data files :

  • combined_data_1.txt

  • combined_data_2.txt

  • combined_data_3.txt

  • combined_data_4.txt

  • movie_titles.csv
    • </ul>

      
The first line of each file [combined_data_1.txt, combined_data_2.txt, combined_data_3.txt, combined_data_4.txt] contains the movie id followed by a colon. Each subsequent line in the file corresponds to a rating from a customer and its date in the following format:

CustomerID,Rating,Date

MovieIDs range from 1 to 17770 sequentially.
CustomerIDs range from 1 to 2649429, with gaps. There are 480189 users.
Ratings are on a five star (integral) scale from 1 to 5.
Dates have the format YYYY-MM-DD.

  • We have 405,041 users in out training set and computing similarities between them..( 17K dimensional vector..) is time consuming..
  • From above plot, It took roughly 8.88 sec for computing simlilar users for one user
  • We have 405,041 users with us in training set.

  • ${ 405041 \times 8.88 = 3596764.08 \sec } = 59946.068 \min = 999.101133333 \text{ hours} = 41.629213889 \text{ days}...$

    • Even if we run on 4 cores parallelly (a typical system now a days), It will still take almost 10 and 1/2 days.

    IDEA: Instead, we will try to reduce the dimentsions using SVD, so that it might speed up the process...

I think 500 dimensions is good enough

  • By just taking (20 to 30) latent factors, explained variance that we could get is 20 %.

  • To take it to 60%, we have to take almost 400 latent factors. It is not fare.

  • It basically is the gain of variance explained, if we add one additional latent factor to it.
  • By adding one by one latent factore too it, the _gain in expained variance with that addition is decreasing. (Obviously, because they are sorted that way).
  • LHS Graph:
    • x --- ( No of latent factos ),
    • y --- ( The variance explained by taking x latent factors)
  • More decrease in the line (RHS graph) :
    • We are getting more expained variance than before.
  • Less decrease in that line (RHS graph) :
    • We are not getting benifitted from adding latent factor furthur. This is what is shown in the plots.
  • RHS Graph:
    • x --- ( No of latent factors ),
    • y --- ( Gain n Expl_Var by taking one additional latent factor)

  • Why did this happen...??
- Just think about it. It's not that difficult.

---------------------------------( sparse & dense..................get it ?? )-----------------------------------

Is there any other way to compute user user similarity..??

-An alternative is to compute similar users for a particular user, whenenver required (ie., Run time)

- We maintain a binary Vector for users, which tells us whether we already computed or not..
- ***If not*** : 
    - Compute top (let's just say, 1000) most similar users for this given user, and add this to our datastructure, so that we can just access it(similar users) without recomputing it again.
    - 
- ***If It is already Computed***:
    - Just get it directly from our datastructure, which has that information.
    - In production time, We might have to recompute similarities, if it is computed a long time ago. Because user preferences changes over time. If we could maintain some kind of Timer, which when expires, we have to update it ( recompute it ). 
    - 
- ***Which datastructure to use:***
    - It is purely implementation dependant. 
    - One simple method is to maintain a **Dictionary Of Dictionaries**.
        - 
        - **key    :** _userid_ 
        - __value__: _Again a dictionary_
            - __key__  : _Similar User_

4.3.2 Transforming data for Surprise models

In [25]:
from surprise import Reader, Dataset

4.3.2.1 Transforming train data

  • We can't give raw data (movie, user, rating) to train the model in Surprise library.
  • They have a saperate format for TRAIN and TEST data, which will be useful for training the models like SVD, KNNBaseLineOnly....etc..,in Surprise.
In [26]:
# It is to specify how to read the dataframe.
# for our dataframe, we don't have to specify anything extra..
reader = Reader(rating_scale=(1,5))

# create the traindata from the dataframe...
train_data = Dataset.load_from_df(reg_train[['user', 'movie', 'rating']], reader)

# build the trainset from traindata.., It is of dataset format from surprise library..
trainset = train_data.build_full_trainset()

4.3.2.2 Transforming test data

  • Testset is just a list of (user, movie, rating) tuples. (Order in the tuple is impotant)
In [27]:
testset = list(zip(reg_test_df.user.values, reg_test_df.movie.values, reg_test_df.rating.values))
testset[:3]
Out[27]:
[(808635, 71, 5), (941866, 71, 4), (1737912, 71, 3)]

4.4 Applying Machine Learning models

  • Global dictionary that stores rmse and mape for all the models....

    • It stores the metrics in a dictionary of dictionaries

      keys : model names(string)

      value: dict(key : metric, value : value )

In [28]:
models_evaluation_train = dict()
models_evaluation_test = dict()

models_evaluation_train, models_evaluation_test
Out[28]:
({}, {})

In [38]:
from surprise import KNNBaseline
  • predicted Rating : ( based on User-User similarity )
\begin{align} \hat{r}_{ui} = b_{ui} + \frac{ \sum\limits_{v \in N^k_i(u)} \text{sim}(u, v) \cdot (r_{vi} - b_{vi})} {\sum\limits_{v \in N^k_i(u)} \text{sim}(u, v)} \end{align}

  • $\pmb{b_{ui}}$ - Baseline prediction of (user,movie) rating

  • $ \pmb {N_i^k (u)}$ - Set of K similar users (neighbours) of user (u) who rated movie(i)

  • sim (u, v) - Similarity between users u and v

    • Generally, it will be cosine similarity or Pearson correlation coefficient.
    • But we use shrunk Pearson-baseline correlation coefficient, which is based on the pearsonBaseline similarity ( we take base line predictions instead of mean rating of user/item)

  • Predicted rating ( based on Item Item similarity ): \begin{align} \hat{r}_{ui} = b_{ui} + \frac{ \sum\limits_{j \in N^k_u(i)}\text{sim}(i, j) \cdot (r_{uj} - b_{uj})} {\sum\limits_{j \in N^k_u(j)} \text{sim}(i, j)} \end{align}

    • Notations follows same as above (user user based predicted rating )

4.4.5 XGBoost with initial 13 features + Surprise Baseline predictor + KNNBaseline predictor

      • First we will run XGBoost with predictions from both KNN's ( that uses User_User and Item_Item similarities along with our previous features.
      • Then we will run XGBoost with just predictions form both knn models and preditions from our baseline model.

Observation

  • All the models have tuned on 25k user dataset
  • Slight reduction in RMSE found for tuned models.
  • Best train result are found in case of knn_bsl_m with minimum rmse of 0.323167
  • Uavg and Mavg features found most important for most of the models.
